Previously Official Rulings

These TCG rulings were issued by Upper Deck Entertainment and have since been deemed unofficial by Konami.[2] They were previously considered official and can still be correct, as long as they follow the official gameplay rules, or unless Konami has issued a ruling that says otherwise.

"Curse of Darkness" inflicts 1000 damage right after the Spell Card is activated, not when it resolves. If the Spell Card's activation is negated however, such as with "Magic Jammer", then no damage is inflicted because the activation was negated.
